Design of a broadband metamaterial absorber for visible solar radiation entrapment
A metamaterial-based ultrathin absorber is proposed in this work using three layers of materials (Tungsten-Silica-Tungsten) for visible solar radiation absorption in which near-unity broadband absorbance is observed in a wavelength span of 380–765nm. The absorber is analyzed by the Finite Integration Technique. The average absorption is 96.86% in this visible domain and the peak is 99.96% at 497.65nm. The structure is investigated for various oblique incident angles and mechanical deformation for utilizing it in a complex solar energy harvester environment. It is found that the structure is wide-angle stable (up to 70°) and mechanically bendable without dropping a significant level of absorption.
